BARBED FENCE.

SPECIFICATION forming part of LettersPatent No. 276,883, dated May l,1883.

` Application tiled December 14, 1882. (No model.)

.To all whom t'mag/ concern Beit known that I, WILLIAM S. RoBEa'rs,

, a citizen of the United States, residing at Boliing is aspecification, reference being had thereupward and the other bentdownward.

in to the accompanying drawings, which i'orm a part of the same, and inwhich- Figure 1 is a perspective view of my invention, and Figs. 2, 3,and 4 are detail views.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of barbed fences in which ametallic strap is provided at intervals with sheet-metal barbs insertedthrough slits in the same; and it consists in the detailed constructionand combination of parts ot' the same, as hereinafter more fullydescribed and claimed.

In the accompanying drawings, the letter A indicates a strap of metal,having at suitable intervals longitudinal Islits b at an equal distancefrom both edges of the strip, through which the barb-plates B areinserted. These plates are cut so as to form arectangular centralportion, a, of the same width as the length of the slits b, and slightlylonger than the width of the strap, and are provided at their upper andlower edgeswith sharp points c. The incisions d, which form the inneredges of these points, form two trapezoidal lips, f, between the pointsupon the upper and lower edge ot' the central portion, ce, ot' the baroplate. The barbplates are fastened upon the straps by inserting themthrough the slits in.

the same, which theytill up, whereupon they are bent at their middle,one halt' being bent The lips f are then bent over the upper and lower ledge of the strap, clasping the same firmly, as shown in Fig. 2, and thebarbs or points o bent to stand out horizontally from the edges ot' thestrap, the barbs upon the same side ot' lips f being bent in oppositedirections, as shown in sectional view, Fig. et, and in Fig. l. In thismanner it will be seen that the barbs are securely fastened to thestrap, they being secured from sliding laterally upon the strap as wellas from falling off it'4 one or more of'the barbs should be broken ott"in the course of time, thus making a very durable fence-barb,

barbed plates and the strap and their manner ot' attachment make it easyand inexpensive to manufacture.

I am aware that barbed fences have been made in which lips projectingfrom barbed plates have been bent over wires, and also that slittedstrips have been used with pointed plates inserted horizontally throughthe slits and twisted on both sides of the same, and I do not claimanyot these constructions, broadly; but

What l'do claim, and desire to secure by Letters Patent of the UnitedStates, is-

In a barbed fence, the combination of the metallic strap A, havinglongitudinal slots b, with the barbed plates B, having points or slots band bent over the edges ofthe strap, in the manner and for the purposeshown and set forth.

In testimony'whereof I at'tix my signature, in presence of twowitnesses, this 17th day of October, 1882.'
